The return of the exiles to the Land of Israel is a powerful mass gathering that merges spiritual elevation with physical wealth. As the people return from all corners of the earth, their destination is Mount Zion, specifically pointing toward the future site of the Temple Mount [רד״ק, ביאור שטיינזלץ]. The primary approach among commentators is that this movement resembles the rushing currents of a river. The people will be drawn together naturally, running with a deep desire to experience the abundant goodness offered by God [רש״י, רד״ק, מצודת דוד]. Alternatively, this forward motion is understood as a state of radiance, where the returning exiles will literally shine with light as they journey [ביאור שטיינזלץ].
The goodness waiting for them exists on two distinct levels: the physical and the spiritual [מלבי״ם]. On a physical level, the returning people will find great economic success, marked by an endless supply of wine, fresh grapes, and rich oil [מצודת ציון, ביאור שטיינזלץ]. This physical wealth pairs perfectly with a profound spiritual satisfaction. Their inner state is compared to a well-watered vegetable garden, representing a complete and vibrant life [ביאור שטיינזלץ]. Just as a continuously watered garden remains permanently saturated and healthy, their souls will be fully satisfied by God's divine goodness [מצודת דוד, מלבי״ם].
Because of this perfect physical and spiritual completeness, the people will never again experience the worry, pain, and sadness that defined their time in exile [רד״ק, מצודת ציון]. The new reality of success and divine favor will completely erase the hardships of the past [מצודת דוד, מלבי״ם]. Instead of grief and lack, their future will be defined entirely by deep comfort, true joy, and absolute cheerfulness [צאינה וראינה].
